The community hub for MeshCore operators in Snohomish County. No towers. No internet. Just LoRa radio and neighbors looking out for each other.
MeshCore is a LoRa-based mesh radio protocol for secure, off-grid text communication — no cell towers, no internet, no infrastructure required. We're building a resilient community network across Everett, Marysville, Monroe, Lynnwood, and the Cascades foothills.
Long-range, low-power radio on the 915 MHz band. Nodes can reach kilometers with line-of-sight — perfect for Snohomish's mix of urban and mountain terrain.
Unlike flood-based protocols, MeshCore uses intelligent path routing and store-and-forward. Messages hop efficiently through repeaters without congesting the network.
End-to-end encrypted direct messages. Public channels for community chatter. Your keys, your network — no accounts, no cloud, no surveillance.
From Everett's waterfront to the Three Fingers peaks, our repeater network is designed to cover Snohomish County's diverse geography — including when the big one hits.
When cell towers go dark during earthquakes, floods, or wildfires, the mesh keeps talking. Several nodes are solar-powered for 72+ hour autonomous operation.
Ham operators, preppers, hikers, and tech enthusiasts all welcome. No license required to listen; a Technician license opens up transmitting privileges.

From zero to transmitting in an afternoon. Here's how to join the Snohomish County MeshCore network.
Popular choices: Heltec V3, LILYGO T-Beam, or RAK WisBlock.
Budget ~$25–$60. Make sure it supports 915 MHz (US band). Check the
MeshCore hardware guide for a full compatibility list.
Download the latest firmware from meshcore.io.
Flash via USB using the web flasher — no special tools needed. Choose Client firmware
to start. Repeater firmware is for fixed, elevated installs.
Download the MeshCore app on iOS, Android, Windows, or macOS.
Connect via Bluetooth or USB serial. The app lets you send messages, view the node map, and manage channels.
Set region to US_915. Join the #snoco public channel
(ask in Discord for the channel key). Set your node name to something identifiable —
callsign holders: use your callsign!
Transmit a test message on the public channel. Then join our Discord
and post your node ID in #node-registry so we can add you to the map.
Welcome to the mesh! 🎉
What's happening in the Snohomish County MeshCore community.
Thanks to KG7SNO, we now have a solar-powered repeater at ~1,240 m elevation near Stevens Pass. This dramatically extends coverage into the Cascades foothills and links us toward Chelan County.
Join us Saturday June 14th at the Everett Makerspace for our monthly meetup. Bring your nodes, ask questions, and help new members get set up. Antenna building workshop at 2 PM.
Snohomish County ARES is running a simulated disaster comms exercise. MeshCore nodes are
invited to participate alongside traditional ham radio. Coordinate via the #ares-exercise channel.
The latest firmware brings improved store-and-forward reliability, faster path discovery, and a new low-power sleep mode. Update recommended for all repeater operators.
Community member W7PNW wrote a detailed guide on optimizing antenna placement for Snohomish County's mix of river valleys, urban density, and Cascade foothills.
The node map has been updated with new signal propagation estimates based on community-submitted RSSI data. Gaps identified near Lake Stevens and Granite Falls.
Find us across the web and on the mesh itself.
